Arsenal's troubles in front of goal look likely to define their season, so maybe they are beginning to regret letting full-back Andre Santos join Gremio on loan.

The Brazilian returned home earlier this month having failed to make a positive impact at the Emirates, but popped up on Wednesday to score in Gremio's 3-0 win against Fluminense in the Copa Libertadores. News of whether any opposition players tried to grab his shirt at the end could not be confirmed.
